摘要
为探明水蒸馏法提取杉木Cunninghamia lanceolata鲜枝叶精油的提取条件,采用单因素法分析样品粉碎方式、液料比、蒸馏时间和NaCl浓度等对出油率的影响。结果表明,采用切草机法粉碎样品,液料比为8:1,蒸馏6 h且不添加NaCl处理的杉木鲜枝叶出油率较高,为0.086%。采用气相色谱质谱(GC-MS)联用仪对精油组分进行解析,共鉴定出48种化合物,其中主要包含29种倍半萜类化合物以及10种单萜类化合物,其质量分别占总质量的88.22%、7.53%。
To investigate the extraction conditions of essential oil from fresh branches-leaf sections of Cunninghamia lanceolata by hydrodistillation,single factor method was used to analyze the effects of sample crushing method,liquid-solid ratio,distillation time and NaCl concentration on the oil yield.The results showed that the oil yield of fresh branch-leaf sections of C.lanceolata could reach a high level of 0.086%when the sample was crushed by the chaff cutter method,the liquid-solid ratio was set to 8:1,the distillation time was 6 h and without the addition of NaCl.After that,the essential oil components were analyzed by gas chromatography-mass spectrometry(GC-MS).A total of 48 compounds were identified,including 29 sesquiterpenoids and 10 monoterpenoids,which accounted for 88.22%and 7.53%of the total mass,respectively.
